Structural Characteristics and Properties of Oil Sludge Sands in Oil Fields

The structural characteristics of oil mud sand in the oil field are particularly complex and diverse, making it very difficult to handle. It is generally composed of structures such as oil-in-water, water-in-oil and suspended solid impurities, and is an extremely stable mixture. The oil components in the sludge sand mainly contain saturated hydrocarbons and aromatic hydrocarbons, and the content of colloid and bitumen is less.

The composition of oil mud sand depends on the geological conditions of the major oil fields, the production technology and the process flow, and is also directly related to the variety of chemicals added, the quality of sewage, and sewage channels. Generally, the moisture content and salt content The amount of ingredients is high. Most of the sludge sands contain harmful substances such as arsenic, mercury, and salts. The characteristics of oily mud sand are mainly high crude oil content, some of which have oil content as high as 50%, high cohesion, and the main binding component of oily mud sand is also crude oil. Oil mud sand dispersed in water will be naturally divided into crude oil floating on the water surface and sand particles sinking to the bottom due to gravity, which mainly depends on the larger component density of oil mud sand. In water, the density of crude oil is lower than that of water.

There is also a big difference in the properties of the old oily sludge sand and the newly produced oily mud sand. The old oily mud sand has a long storage time, so there will be light components diffused during the long-term storage process, while some crude oil is due to the separation of seepage. The physical and chemical reactions of oil sludge will greatly change the properties of oil sludge, and therefore will slowly transform into a mixture of heavy oil, asphaltene, sand and soil.

Based on the above-mentioned structural characteristics, components and properties of oily sludge sand in the oil field, it is explained that the harmful components of oily sludge sand in the oil field are more and more complex, especially in the process of oil production, the addition of various chemicals will increase the toxic components of the oil sludge. These toxic components not only increase the difficulty of separation and purification of the oil sludge, but also more seriously, if the oil is directly discharged , Because the toxic substances are seriously exceeding the standard, the direct and arbitrary discharge will cause serious environmental pollution.

The function and classification of KOSON mud guns

KOSON mud gun relies on the high-pressure fluid flow in the mud pipeline to generate high-pressure jet impact force through the nozzle of the mud gun to flush the sediment at the bottom of the drilling mud tank to make it suspended.

The main function of the KOSON mud gun is: auxiliary mud agitator, right the corners of the mud tank, the bottom edge of the mud tank and the deposits of the suction ports of each pump are prevented from depositing, and then the agitator is used for uniform mixing. After the agitator stops running for a period of time, the agitating impeller will be buried by the deposited sediment. Before it needs to be re-run, the KOSON mud gun can reduce part of the resistance when the agitator is started, which provides a guarantee for normal operation.

KOSON mud gun is divided into high-pressure gun and low-pressure gun. Because the high-pressure mud gun is a tributary supply of drilling pump, its pressure level can reach 1～6MPa; as for the low-pressure gun, it is supplied by sand pump, and its working pressure level is 0.2 ~0.3MPa. In general, the number of KUSON mud guns should be determined according to the number of mud mixers.

What are the characteristics of oil and gas reservoir drilling fluid?

Oil and gas reservoir drilling fluid is the “blood” of drilling and plays a very important role in drilling operations. Therefore, the requirements for drilling fluid are very high, according to the characteristics of different oil and gas layers, matching different types of drilling fluids. This article roughly summarizes the following four types of oil and gas reservoir drilling fluids and the characteristics of oil and gas reservoir drilling fluids.

1) Oil and gas reservoir drilling fluid-water-based drilling fluid

Water-based drilling fluid refers to the general term of various circulating fluids that meet the needs of drilling work with its multiple functions during oil and gas drilling.

Features of water-based drilling fluid: Low cost, Simple slurry preparation, Relatively low pollution.

2) Oil and gas reservoir drilling fluid-oil-based drilling fluid

Oil-based drilling fluid features: good lubricity, little damage to oil and gas layers, and good for stabilizing the borehole wall. It is widely operated on various drilling platforms. Oil-based drilling fluid also has the characteristics of resistance to high temperature, salt and calcium erosion.

3) Gas drilling fluid is formed by injecting air or nitrogen into conventional drilling fluid. Characteristics of gas drilling fluid: Compared with ordinary drilling fluids, it has the advantages of fast speed, short cycle and low overall cost.

4) Oil and gas reservoir drilling fluid-synthetic base drilling fluid

Synthetic-based drilling fluids are often characterized by easy biodegradation, no pollution to the environment, and pollution discharge standards that meet national environmental protection requirements; the filtrate is the base fluid instead of water, which has good performance in stabilizing the well wall and protecting oil layer gas; the conventional performance is stable, easy to control and operate, the liquid phase has a high viscosity, which is good for suspending and carrying drill cuttings, and has high thermal stability, which can still meet the needs of carrying cuttings at high temperatures.

The composition and physical treatment method of drilling waste

The composition of drilling waste is complex, generally alkaline, with a pH value of 8. 5-12, and the solid particle size is generally 0.01 to 0.3 μm. The appearance is generally viscous fluid or semi-fluid, with fine particles and grades. Various chemical treatment agents are added to it, generally containing heavy metals, oils, bentonite, alkalis and compounds (including organics), etc., such as iron chromium salt, sulfonated pitch, sulfonated tannin extract, sulfonated lignite, etc. Livestock and environmentally harmful substances. Waste fluids are produced in the process of oilfield exploration and development, such as cleaning fluids, drilling fluids, and sewage (formed by rainwater washing the well site with some mud and oily substances). The harmful substances are mainly oily substances, and there are also a small amount of them. Organic treatment agents, heavy metals and alkali substances have higher CODCr values. During the drilling process, the mud circulates in the drill bit to lubricate the drill bit while also carrying the drill cuttings to the ground. Most of the drill cuttings are solid particles, and a small part is mixed in the drilling fluid in the form of mud sand, accounting for about 20% of the total waste. Contaminants are mainly drilling fluid.

At present, domestic and foreign drilling waste treatment methods mainly include chemical and physical methods such as chemical flocculation, solidification, washing, incineration, destabilization, and landfill. After chemical flocculation treatment, it can be directly discharged in accordance with environmental protection requirements, or be recycled to prepare mud, or injected into wells, but it lacks efficient and economical flocculants, and the harmful substances after chemical solidification are no longer diffused and migrated to the environment. The solidification treatment requires a certain cost, and the amount of one-time treatment is large. The landfill method has an adverse effect on the surface water and its irradiated soil. The incineration method has a high treatment cost and will cause secondary pollution to the air. Although these methods have processed the drilling waste mud to a certain extent, the organic pollutants in the drilling waste mud have not been decomposed and may still pollute the environment.

Mud treatment equipment can control the specific gravity and viscosity of the mud

Mud treatment equipment is a kind of pile foundation auxiliary machine that can control the mud performance index in the construction of mud wall protection. It can achieve strict control of the specific gravity, viscosity and sand content of the mud. This type of equipment can be used for mud purification treatment. The mud waste produced in the purification process is subjected to dry discharge treatment, and the treated mud can be recycled and reused, so the transportation and treatment cost of construction mud can be greatly saved.

The mud can be used as a lubricating and cooling agent in the construction of the pile foundation between the use of mud and processing equipment. It can cool the tools while washing the tools, prevent the wall from collapsing or peeling, and maintain the dug shape unchanged. In addition, when the construction pile hole is poured, the quality of the mud will also affect the end bearing effect of the cast-in-place pile. Therefore, according to the different construction process requirements, certain standards and requirements for the quality of the mud will inevitably be put forward in the mud making process. Therefore, in the process of mortar making, how to stably control the sand content and specific gravity of the mud has become a key factor in controlling the hole formation and pile quality of cast-in-place piles.

As a high-efficiency and energy-saving construction mud purification and reuse device, mud treatment equipment has obvious technical and economic advantages in terms of the quality of construction slurry and the cost of waste slurry treatment. High comprehensive benefits are produced in terms of quality assurance and pulp cost.
